Hands-On Software Engineering with Golang

By: Achilleas Anagnostopoulos

Overview of this book

Over the last few years, Go has become one of the favorite languages for building scalable and distributed systems. Its opinionated design and built-in concurrency features make it easy for engineers to author code that efficiently utilizes all available CPU cores. This Golang book distills industry best practices for writing lean Go code that is easy to test and maintain, and helps you to explore its practical implementation by creating a multi-tier application called Links ‘R’ Us from scratch. You’ll be guided through all the steps involved in designing, implementing, testing, deploying, and scaling an application. Starting with a monolithic architecture, you’ll iteratively transform the project into a service-oriented architecture (SOA) that supports the efficient out-of-core processing of large link graphs. You’ll learn about various cutting-edge and advanced software engineering techniques such as building extensible data processing pipelines, designing APIs using gRPC, and running distributed graph processing algorithms at scale. Finally, you’ll learn how to compile and package your Go services using Docker and automate their deployment to a Kubernetes cluster. By the end of this book, you’ll know how to think like a professional software developer or engineer and write lean and efficient Go code.

Selecting an SDLC model for our project

Before delving into the details of the Links 'R' Us project, we need to consider the SDLC models we discussed in Chapter 1, A Bird's-Eye View of Software Engineering, and select one that makes more sense for this type of project. The choice of a suitable model is of paramount importance: it will serve as our guide for capturing the requirements for the project, defining the components and the interface contracts between them, and appropriately dividing the work to be done in logical chunks that can be built and tested independently of each other.

In this section, we will outline the main reasoning behind the selection of an Agile framework for our project and elaborate on a set of interesting approaches for speeding up our development velocity using a technique known as elephant carpaccio.
